The 3 phase power transformer is a core electrical equipment designed for three-phase AC power transmission and distribution, converting voltage levels to ensure efficient and safe power supply. Manufactured by Baoding Tianwei Baoqian Power Equipment Co., Ltd. since 2004, this 3 phase power transformer adopts high-quality cold-rolled silicon steel sheets for the iron core and advanced winding technology, delivering stable performance in harsh conditions. The 3 phase power transformer is available in oil-immersed and amorphous alloy types, with no-load loss reduced by 35% compared to GB/T6451, meeting national energy-saving requirements. It is widely used in power grids, industrial parks, and key projects, supported by ISO9001, ISO14001, and ISO45001 certifications.
